Water power

In this part we will explore the possibilities for generating energy with water.

The oldest way to generate energy is by running a paddle wheel in running water. The next step was to also add a height difference, which resulted in more power.
Nowadays, many variations have been developed that use tides, currents, pressure due to height difference and wave stroke.

Hydrogen is both energy and an opportunity to store energy. Hydrogen is made by splitting water into hydrogen and oxygen. If more electricity is produced, if needed, the surplus could be used to split water. Later the stored hydrogen can be converted back into electricity but also directly into heat or mechanical energy.

Drinking water

Drinking water is water that is clean enough for people to drink safely. The FFABW believes that everyone is entitled to this basic need for people. That is why we strive to include this component in our installation. Making drinking water costs energy. The trick is to make as much drinking water as possible with as little energy as possible by recycling the waste water on site. Replenishing water is easy when there is rain. In a number of cases it is possible to collect codens water if it cools down at night. More energy is needed for pumping water from the ground. There are other processes for making drinking water, but that require even more energy.

Not all options can be applied to make a home autarkic. There will be other options depending on the location on earth. The appropriate they will certainly be developed.
